问题：如何才能限制用户对自己对象的DDL权限（触发器实现）?

解决此问题的示例：


create or replace trigger ddl_refuse_trig
before ddl on schema
declare
v_ipaddress varchar2(20);
begin
select sys_context('userenv','ip_address')
into v_ipaddress from dual;
if v_ipaddress <> '192.168.1.152' then
raise_application_error(-20099,'Sorry,You
can not execute the command.Please contact the DBA',false);
end if;
end;
